APPARATUS FOR MAKING CORRUGATED PAPER.

SPECIFICATION forming part of Letters Patent No. 654,884, dated July 31, 1900.

Application filed J ul 20, 1899.

To all whom it may concern: 7 Be it known that we, JEFFREY T. Fnanns and AINSLIE W. FERRES, residing at Ander son, in the county of Madison, in the State of Indiana, have invented a certainnew and useful Improvement in Apparatus for Making Corrugated-Paper, of which the following is a description, reference being had to the accompanying drawings, forming part of this speci fication.

Our invention has for its object the provision of an efficient means for cor'rugating continuous strips of paper longitudinally instead oftransversely, as usual, such longitudinallycorrugated paper possessing advantages over the common transverselycorrugated paper for certain purposes not necessary to be de-- scribed.

The novelty of our invention will be hereinafter set forth, and particularly pointed out In the accompanying drawings, Figure 1 is a diagrammatic view, inside elevation, of one form of our novel apparatus; Fig. 2, a top plan view of the same; Figs. 3 and 4, detail views of the gathering-rollers; Fig. 5, a detail of the finished corrugated strip; Fig. 6, a view. corresponding to Fig. 1, showing the substiturollers of Fig. 1; Fig. 7, a top plan view of Fig. 6; Figs. 8 and 9, detail views of the gathering-fingers; Fig. 10, a detail View of the guides between the heater-plates, and Fig. 11 an enlarged sectional detail of two of the intermeshin g corru gatin g-rollers.

We produce the longitudinally-corrugated strips of paper in our novel apparatus by gradually gathering or folding the strip of plain paper into corrugated form as it advances,

from the full width of the plain paper to the width of the corrugated strip, and then passing such gathered or folded strip between intermeshing heated corrugating-rolls,by which the longitudinal corrugations in the strip bea come firmly set. If the corrugated strip is to be faced, then the strip or strips of facing-paper will be,applicd with suitable paste to the strip of corrugated papenafter the latter has passed through the corrugating-rolls and the corrugated strip, witlpthe applied facing strip "the supply-roll.

or strips,be then drawn between suitable heaters to dry the same.

Our novel apparatus consists of suitable per drawn in a partially-dried condition from (Not shown.)

5 B represents a series of gathering-rollers,

each'eonsisting of a curved spindle or axle a, having mounted to turn upon it a series of equidistant disks I). These rollers 13 are arranged in pairs one above the other, and

the disks b of the rollers of the succeeding pairs are arranged at a gradually-decreasing distance from each other, as shown in Fig. 2. Likewise, as shownin Fig. 1, the spindles or axles ofthe rollers of the succeeding pairs are arranged at gradually-decreasing distances from each other to cause a gradual increase in the depth of mesh of the disks upon the rollers of the succeeding pairs. shown in Fig. 1, and more particularly in Fig. 3, the two rollers of the first pair (at the left) are set at such distance from each other that their disks but slightly overlap or interinesh, so that as the strip of plain paper is drawn between the rollers of this pair it-will be but slightly indented or creased. The

rollers of the next pair are set a little closer together, so as to indent or crease the paper a little deeper, and their disks are likewise a little closer together upon each roller, so as to draw the paper inward slightly; and so on to the rollers of the last or right-hand pair, which, as shown in Figs. 2 and 4-, areso set with relation to each other that their disks will intermesh to substantially the full depth of the corrugations to be formed, while their disks are also located so close together upon each roller as to bring the longitudinal corrugations ol' the strip immediately adjacent each other in position to enter between the. heated corrugating-rolls C. There are in the present instancethree pairs of these rolls of too the form shown more particularly in Fig. 11, but more or less of them can be used, and they serve to dry the paper and give the corrugations theirtrue and final form and firmly set them. If the corrugated strip is not to be faced, it will be delivered in completed form from'the roll 0 and can be cut into suitable length for the desired use or for convenient storage and shipment. If, however, the corrugated strip is to be faced, paste will be applied to one or both sides of it as it emerges from the rolls 0 by paste-rolls D and the facing-strips E'be led from suitable supply-rolls over rollers F, between which the corrugated strip is drawn and by which the strips E are pressed against its opposite.

faces. From the rollers F the three strips are drawn forward between the heater-plates G, by which the facing-strips are maintained in firm contact with the corrugated strip while the paste is being dried. The heaterplates G may be of any suitable construction, and any suitable means in rear of the heaters may be employed for drawing the strips through the heaters. If single-faced paper is to be made, one of the paste-rolls D and one of the facing-strips E will be dispensed with.

For the purpose of preventing the opposite edges of the strip being flattened out by the heater-plates G as the strips are drawn between said heaters, we have provided the adjustable guides H, (shown in Fig. 10,)by which nary corrugations init.

the opposite edges of the strip will be confined and prevented from being pressed outward.

In Figs. 6 to 9 we have illustrated the employment of gathering fingers or guides I in place of the gathering-rollers B for forming the preliminary corrugationsin the paper strip preparatory to its entrance between the corrugating-rolls (J. As will be readily understood from the drawings, these fingers or guides I are relatively arranged similarly to the guide-rollers B and serve the same purpose in gradually contracting the width of the strip of paper and forming the prelimi- These guide-fingers may be satisfactorily employed in place of the guide-rollers B for corrugating comparatively-narrow strips of paper; but where wide strips are to be corrugated it is desirable to employ the rollers B on account of the decreased friction incurred.

Having thus fully described our invention, we claim 1. The herein-described apparatus for making longitudinally-corrugated strips of paper, comprising gathering or folding means for indenting or creasing a plain strip of paper along'gradually contracting and deepening longitudinal lines, to form preliminary longitudinal corrugations, and corrugating-rolls to receive such strip of paper and finish and set the longitudinal corrugations therein.

2. The herein described apparatus for forming longitudinally-corrugated faced paper, comprising gathering or folding means for indenting or creasing a plain strip of paper along gradually contracting and deepening longitudinal lines, to form preliminary longitudinal corrugations, corrugating-rolls to receive such strip of paper and finish and set the longitudinal corrugations therein, means for applying paste and a facing strip or strips to the corrugated strip as the latter emerges from the corrugating-rolls, and suitable heaters between which the several pasted strips are drawn to dry them and secure them together.
